I kind of think the problem with this show is the premise. Ironically, it's also what I like about it. Contestants are frequently criticized for creating something that doesn't taste like a dish they may not be familiar with, and while you could say they should know the world cuisines, I still think there's something strange about it. Still, it's a fun show, and you learn a lot about cooking around the world. In someways, the elimination rounds are the best part.
The host is also not a good fit.
